Due to the characteristics of the ingredients, it is recommended to start with a small amount and gradually increase the amount while observing your skin's reaction. <For customers experiencing retinol*1 for the first time>・Start with a small amount when you first begin using it to allow your skin to comfortably get used to retinol*1. After that, use an appropriate amount while observing your skin's reaction.・If you are concerned about irritation, it is recommended to use it after a cream.・Please read the instructions for use and precautions carefully before use. <Precautions when using>・During pregnancy or breastfeeding, your skin is especially sensitive, so it is recommended to refrain from using it.・Do not use immediately after laser or wax treatment.・Physical exfoliating products such as scrubs may cause irritation, so it is recommended to avoid using them at the same time as much as possible.
